该文研究了在全彩色ＬＥＤ显示系统中应用基色转换技术实现图像的真彩色显示。由于彩色ＬＥＤ显示屏所选用的三基色与电视系统三基色在光谱特性上有着较大差别，同一颜色在２个不同的色度系统中，其三刺激值必然不同。为了真实地再现视频图像信息，ＲＧＢ信号在送给彩色ＬＥＤ显示屏之前必须进行基色变换处理。文中叙述了基色转换的方法，并针对实际系统给出其彩色校正矩阵及其硬件实现。实验结果表明，通过校正处理能有效地减小颜色再现色差，提高图像的视觉质量。
This paper studies the application of primary color conversion technology in the full-color LED display system to realize the true color display of the image. Because of the three colors of the three primary colors selected by the color LED display and the three primary colors of the television system, there are big differences in the spectral characteristics. The tristimulus values of the same color in two different colorimetric systems are necessarily different. In order to truly reproduce video image information, RGB signals must be subjected to a primary color conversion process before being sent to a color LED display. The paper describes the method of color conversion, and gives its color correction matrix and its hardware implementation for the actual system. Experimental results show that color correction can effectively reduce color reproduction and improve the visual quality of images.
